I'd choose a German TBA from a great producer and recent good year. Since my demise is hopefully 20+ years away, this bottle should be in great condition and ready to drink then. Maybe a Robert Weil or Vollrads.

Once upon a time I did not care for pinot noir, but signed up for a special wine tasting featuring eleven 1990 Burgundies (all poured and laid out in front of me at the same time in proper stemware), and which lineup included two DRC's and a Leroy. I did not expect to love the wines--I'd never had burgundy before, only Cali pinots--but signed up anyway considering it essential to my wine education. But love I did. I had never smelled anything so darned grand, not even close. Never before had wine contemplation made me want to become tiny so that I could swim in the bowl: smelling it, tasting it wasn't enough, I wanted immersion. The Leroy was my favorite.

Probably because it was the first time and maybe the only time I've ever been presented with the luxury I came to understand that evening was, I've never had another experience so profound. And though it may require a certain virgin state to have the same impact that it once did, if I could have another bottle of a young Leroy Auxey Durress from a rich, ripe year on the very last day of my life in which I was to taste wine, it might just convince me that if there were no heaven waiting beyond then that glass of heaven right here on earth is the next best thing.

My wine shopping and I have never had a problem. Just a perpetual race between the bankruptcy court and Hell.--Rogov

It's kind of a grim question, but assuming the departure is of a fairly humane nature (i.e. not awaiting execution in a prison cell, where I might want something more fabulous to transport me away), I'm thinking something sentimental would be called for. Some of the wines that I first enjoyed as a winelover, maybe Foillard Morgon, Breton Chinon/Bourgueil, or zesty German riesling from any number of producers.

Your question brings to mind the famous last words of the great economist John Maynard Keynes. When asked on his deathbed if he had any regrets, he replied that "I wish I'd drunk more champagne." I personally am working diligently toward not having that regret. So in answer to your question, it would be the best bottle of champagne i had.

Seriously, it would probably be an exceptional red Burgundy for me. Maybe a Musigny or La Tache. I've never had either of these Grand Cru wines so I am assuming that I would love them with the proper producer, vintage and cellaring.
